Patented sept. 16, 1930 j RAYMOND BARRAS, 0F PARIS`, FRANCE SEEATH CRAYONIEOLDER Application led February 14, 1980. lSerial No. 428,315.

The present invention relates to improvements in sheath holders for charcoal and other crayons and similar articles for-drawing or other purposes. l

More particularly, the object of the invention is to provide by avery. simpleconstrucj tion a practical and easily manipulated sheath crayon holder.

An object is also to simplify the opening and closing of the sheaths of crayon holders as hitherto constructed.

A further object is to avoid any possibility of spoiling and breakage of the crayon or the like `on opening and' closing the sheath by avoiding any possibility of contact between the crayon and the cover.

Finally an object of the invention is to produce asheath crayon holder capable of being employed for other uses by the draughtsman.

A sheathcrayon or the like holder for the above purposes has the features described in 'the following description and set forth particularly in the claims annexed to the end thereof.

A sheath crayon or the like holder accord ing to the preferred form of the invention isv illustrated on the accompanying drawings, in which z- -V Fig. l is an elevation of the sheath crayon holder open, the `upper portion beingfin section.

, Fig. 2 is a vertical section of the crayon holder sheath along the line 2-2 of F ig.\1.

Fig. 3 is a transverse section of the sheath crayon holder along the line 3-3 of Fig. 1. Fig. 4 is aview showing the opening of the crayon holder forenabling it to be used for 'w the purpose of making/a drawing.

Fig. 5 is an elevation of the `closed'crayon holderready for use as an eraser.

The sheathfl of the crayon holder shown rectangular in cross section with rounded edges is closed by a cover.2,embos,sed at 3 against which the thumb of the user canbe applied for opening such cover.

. .The cover 2.is pivoted at 4to a plate 5 s1id- Y in along the face of the sheath 1 and pro-l4 vided with avstem 5 ,which itself slidesin .a slot 7 in the sheath 1.A The cover cani thus` 'of the sheath and'of the slideway' 14.

cases the cover is maintained applied against the sheath 1 by a spring 35 enwrapping the hinge 4 and bearing against the cover. The crayon 8 is inserted in a cup 9 and held therein by small plate springs 10', the cu being slidable longitudinally of an inner tu ular portion l'mounted in the sheath 1 and provided with a slideway 14.

The connection .between 'the cover 2 and the crayon 8 is provided by a band 11 arranged inthe slideway 14 and secured on one side of the holder to the guide stem 6 of theslide plate 5 and on the other side to a screw 12 screwed into the cup 9.

The band 11 is di laceable between t-he tube 13 mounted insig e the sheath 1 and a slideway 14 also secured inside the sheath 1,

such arrangement ensuring the guidanceof the band 11v on its displacement.

Two slots 15 and 16 are formed respec tively in the'slideway 14 and in the inner tube 13 which permit the -gu-ide stem 6 of the cover 2 and the screw 12 ofthe cup 9 to slide freely.

The sheath crayon holder has at its -lower end an externally screw threaded socket 25,

which is secured lby any suitable means., such as soldering, on the base 26 ofthe sheath.

A rubber 27 is mounted in the socket 25 for erasing pencil or ink marks. y

Finally on the socket is screwed'by its'internally screw threaded cylindrical portion 28, a truncated conical crayon Sharpener 29, provided with blades 30 and having 'an aperture 31 for the escape of chips from the sharpcned crayon.

The sheath crayon holder thus constructed is used in .the following manner: The draughtsman takes the closed sheath (Fig.'4) in the hand,applies the thumb tothe boss 3 of the cover 2, which causes the cover to tilt in the direction of the' arrow32 about the 05 hinge 4, then the sliding of the whole cover -2 and slide plate 5 in the direction 34 along the face of the sheath -1,rthe guide stem"6 itself sliding in Athe longitudinal grooves 7 and 15 v TheA band 11 is thrust by the cover 2 during this movement and itself slides in the direction of the arrow 33 between the inner tube 13 and the slideway 14. The cup 9 participates in this movement and carries therewith the crayon 8 which thus is projected from the sheathl. The sheath crayon holder is thus open'and can vbe used by the draughtsman for the making of any drawing Whatever.

In order to close the sheath 1 it suiiices to carryout the above operations in the reverse direction.

The band 11 being positively connected to the cup 9 by the screw 12, draws the cup and the crayon 8 in the inverse direction to arrow 33; the crayon thus progressively recedes into Lthe sheath without liability oncoming in contact at any timewith the cover-2 nor of being broken by such cover, the movements of the crayon 8 and of the cover 2 being simultaneous and opposite in direction.

The guidance of these various sliding .movements is effected in asure and precise manner by the band 11 sliding between the inner tube 13 and the outer slideway 14 and by the sliding of the stem 6 and of the screw 12 respectively in the grooves 7, 15 and 16.

vIt is to be noted thatthis movement is very convenient; the draughtsman can in fact efplacement, whatever be the' nature of the article constitutin the rod 8; in particular such rod instead of eing a stick of crayon may be a lip-stick. The mechanism in such case still avoids any contact between the cover and the lip-stick and any spoiling of such stick thereby.

Claims:

1. In a sheath holder for a crayon, an outer sheath bod having a slot, a slide displaceable along the s ot, a cover mounted on the slide so that the cover can slide along the sheath, and connecting means interposed between the cover and the rod so that said rod issues from the sheath or recedes thereinto according to the direction of displacement of the cover.

2. In a sheath holder for a crayon, an outer sheath body having a slot, a slide displaceable along the slot, a hinge provided on the slide, a cover pivoted on said hinge and having a boss which-enables the cover to beslid along the sheath then to tilt easily about the hinge for closing the mouth of the sleeve, and connecting means interposed between the cover and the rod so that said rod issues-from the sheath or recedes thereinto according to the direction of displacement of the cover.

In testimony whereof I have signed this specification. e

fect it with one hand, without any difficulty.

It happens that after a certaintime ofluse 1 the crayon has need of being sharpened.

In such case'thedraughtsman has recourse to the crayon 'Sharpener 28 which is located at the lower end of the sheath. For this purpose he unscrews the crayon Sharpener which embraces the socket 25 applied to the bottom of the sheath 1 and uses it in the usual manner, that is to' say by turning the crayon Sharpener 28 with blades 50 on the crayon 13. The chips escapeby the 'aperture 31. f

Finally 1t may happen in the course of his workthat the draughtsman may desire to 4make alterations -in his drawing. In such case he can erase the incorrect work by using the rubber 27 which'is mounted in the socket 25 at the lower portion of the sheath 1.

To summarize, by the present invention a very practical and very convenientl sheath. crayon holder is provided.,

used e his inventlon also avoids any possibility of theV holder spoiling the crayon by the fact that the crayon can never enter into contact' with the cover nor scrape against the sides of the sheath. Finally this invention enables the artist or draughtsman to have combined in a.

single articlel as a cra on s apener and rubber.

The a ove device has been described-assume. 1n that the invention is applied to acrayon l. ho der. But the linvention extends obviously e to various mechanical details of the device,

indispensible accessories such particularly to that connectin the cover 2 to the cup 9, in one or the other dgirection of dislao
